I work on a remote small team, but we work on a highly complex, large code base. We rarely pick up a phone, and we do not use email. Everything is 100% Slack.

I work on a remote small team, but we work on a highly complex, large code base. We rarely pick up a phone, and we do not use email. Everything is 100% Slack. This works well for us. You can bring in only the people you need, you can "star" messages and channels that are important, and none of us have any time to spam/meme the channels, so it's 100% business. We integrate the JIRA slackbot to keep abreast of what is going on in JIRA. It all "just works" for us.
